Abstract

The change in the voltage between the electrodes of a gas discharge plasma when illuminated at wavelengths corresponding to allowed transitions in the gas atoms has been measured for cesium, uranium, argon, neon, hydrogen, and mercury plasmas. Using this effect, high signal-to-noise absorption spectra were obtained with a mechanically scanned cw Rh6G dye laser. Magnitude, polarity, and saturation of the induced voltage charges were determined; a 30% decrease in the operating voltage of a cesium discharge tube was the largest effect observed.
